GROW KR501 Fingerprint Module With Control board - 20 Fingerprint Capacity
The GROW KR501 Fingerprint Module with Control Board is a compact biometric fingerprint recognition solution designed for secure authentication and access control applications. With a storage capacity of up to 20 fingerprints, it enables users to register and verify authorized fingerprints for reliable identity authentication. The integrated control board simplifies system integration and helps developers incorporate fingerprint-based security into electronic projects and embedded systems.
Designed for applications requiring convenient and secure user identification, the KR501 fingerprint module is suitable for smart door locks, electronic access control systems, attendance management devices, security equipment, and DIY biometric projects. Its compact design makes it a practical choice for embedded applications where space efficiency and fingerprint-based authentication are important.
Specifications
- Fingerprint Capacity: 20
- Working Voltage: DC 3.7-10V
- Standby Current (excluding external equipment): 2.5-7uA typical value: 3uA
- Working Current (excluding external equipment): 40-250mA typical value: 45mA
- Output: 1second, 3.3V-500mA
- Low voltage alarm: ≤4.8V
Operation Instruction
After the fingerprint is passed, the OUT1 pin outputs a signal with a voltage of 3.3V and a current of 500ma for 1 second. In the initialization state, any fingerprint can pass through.
- Register Fingerprint:Long press the registered fingerprint(In initial state press any fingerprint), until the blue indicator light turn on and hearing music, means the system in register state, press the finger with multiple times in fingerprint collection area,each press have “di” sound, until hearing music means fingerprint register successful. Fingerprint can be registered continuously when system in register state; if no need adding fingerprint more, waiting a few seconds.
Note: In the initialization state,must have to register more than 2 correct fingerprints for the first time,then the system can be removed from the initialization state.
- Delete Fingerprint(Back to initialization state):
- Long press the registered fingerprint, until the red indicator light turn on,means all fingerprints are deleted and back to initialization state.
- Use INIT_KEY pin. In the standby state, make the INIT_KEY pin ground connection, until the red indicator to turn on, hear the “Di-” sound, disconnect the grounding, the indicator turns green, means all fingerprints are deleted and back to initialization state.
Package Includes
- 1x GROW KR501 Fingerprint Module With Control board - 20 Fingerprint Capacity
